Subject: ATA devices are now asynchronous.  The ATA layer itself now performs
 the async_wait(), though we may wish to move this higher up the stack, and
 consider making the block device model asynchronous.  (There is only a
 marginal cost for synchronous devices, since they can simply call
 async_done() before returning; async_wait() will work seamlessly in this
 situation).
